Recent climate projections indicate substantial environmental alterations in oceanic island
regions during the 21st century, setting up profound threats to insular floras. Inherent …

Climate change is taking place more rapidly and severely in the Arctic than anywhere on the
globe, exposing Arctic vertebrates to a host of impacts. Changes in the cryosphere dominate …

Sympatric species are expected to minimize competition by partitioning resources,
especially when these are limited. Herbivores inhabiting the High Arctic in winter are a prime …

Arctic wildlife is often presented as being highly at risk in the face of current climate warming.
We use the long-term (up to 24 years) monitoring records available on Bylot Island in the …

In seasonal environments, breeding events must be synchronized with resource peaks to
ensure production and growth of offspring. As changes in climate may affect trophic levels …

In highly seasonal environments, timing of breeding of organisms is typically set to coincide
with the period of highest resource availability. However, breeding phenology may not …

Determining the manner in which food webs will respond to environmental changes is
difficult because the relative importance of top‐down vs. bottom‐up forces in controlling …

The Arctic is viewed as most sensitive to climate warming and subject to a general greening.
Yet, summer weather conditions, which differ greatly among years, are believed to have little …

Arctic sea ice decline has led to an amplification of surface warming and is projected to
continue to decline from anthropogenic forcing, although the exact timing of ice-free …

Accurately simulating the physical properties of Arctic snowpacks is essential for modeling
the surface energy budget and the permafrost thermal regime. We show that the detailed …
